WINDOW FRAME AND SASHES.

Specification of Letters Patent.

Patented June 9, 1914.

Application filed March 1, 1913. Serial No. 751,411.

To all whom it may concern Be it known that 1,; ELOF R. LEONARD, acitizen of the United States, residing at Woodclifi', in the State ofNew Jersey, have invented certain new and useful Improve ments in WindowFrames and Sashes, of which the following is a specification.

My invention relates to window frames and sashes so arranged that thesashes may not only be raised and lowered, vertically, but that they mayalso be tilted or inclined at an angle to the vertical, as well asreadily removed from and replaced in the frame, all as hereinafter morefully described and claimed.

In the drawings Figure 1 is a vertical, sectional view of my improvedwindow frame and sashes; Fig. 2 is a similar view of the window frame,but it shows the sashes in full lines and set at an angle to thevertical; Fig. 3 is a top view partly in section of the frame andsashes, the upper part of the frame and the left hand portion of theupper sash being shown in section; and Fig. 4 is a front view, shortenedby breaking away portions, of one side of the frame, sashes andattachments.

Corresponding reference numerals designate corresponding parts in allthe figures.

The frame 1 is preferably made of sheet metal, and is provided withfront stops 2 and 3 for the outer and inner sashes respectively. Thesefront stops, 2 and 3, are preferably provided with grooves 41 and 5adapted to receive flanges 6, 7 forming weather strips on the edges ofthe respective sashes. In the inner side of the frame are also formedvertical grooves or recesses, in which travel the pivots 10, 10 and 11,11 of the upper and lower sashes. These pivots also serve as anchors forthe chains 12, at either side of the frame, each of which chains runsover a pulley 13, in the top of the frame, so that the sashes act ascounterbalance weights, each for the other.

The upper sash is provided at or near its top on one or both sides witha sliding bolt 14, which may be projected into the groove 8, so as toretain the sash ina vertical position in the frame.

The side of the frame is provided with an upper sash stop, which isshown in the drawings as consisting of a sliding bolt which can beentirely housed within the frame or pushed out therefrom so as tointercept and support the upper sash when it is swung forward, as shownin Fig. 2. And it will be seen that, in consequence of this arrangement,the upper sash may be lowered slightly, the bolts 14: withdrawn from thegrooves 8, the bolt 15 projected, and the sash swung inward upon itspivots 10, 10 into the inclined position shown in Fig. 2, where it willbe supported by the stop-bolt 15; the angle at which it is inclinedbeing governed by the point at which the stop-bolt is placed in theframe. If it is desired, the stop-bolt 15 may he slid. out of the pathof the upper sash, and the sash may be lowered into a substantiallyhorizontal position where it may be supported by the top of the lowersash, when the latter is inclined inward, as shown in Fig. 2.

To one side of the lower sash is attached a bracket 16, carrying aswiveled guide head 17, through which slides a curved rod 18, pivoted atits upper end to a sleeve 19 which slides in the frame-groove 9. Thechain 12 travels freely through the sleeve 19, which, however, isprevented by the chain from leaving the groove 9. The lower end of therod 18 is provided with a detachable screwknob 20, or other suitablemeans for preventing its slipping out of the guide 17; and it may belocked in any desired position in the guide 17 by means of the set screw21 mounted therein. This arrangement permits the top of the lower sashto be swung in from the frame, to any distance permitted by the lengthof the rod 18, and to be locked at the desired position by means of theset screw 21. As the sash is swung in, the sleeve 19 will slide down thechain lowering its end of the rod 18, thereby increasing the distance towhich it will permit the sash to be swung in. In this manner the upperpart of the lower sash may be swung inward without raising it free ofthe sill, and with out moving the upper sash from its ordinary verticalposition. And the lower sash may also be raised and lowered in the framewhile in its inwardly inclined position.

By removing the screw-knob 20 from the end of the rod 18, and slippingthe rod out of the guide 17, the lower sash may be lowcred into ahorizontal position, and its pivots 11 removed from the grooves 9 bytilting the sash sidewiso, so that the sash may be taken entirely out ofthe frame for cleaning, repair or other purposes. In this case the uppersash may be allowed to slide down to the bottom of the frame. Or thebottom sash may be allowed to turn upside down, its weight beingsupported by the upper sash. Again, the lower sash may be raised, andheld up by any suitable means, as for instance the sliding bolt 22. Thiswill bring the top of the upper sash, when lowered,

and the top of the upper sash is provided with a tongue 27 cooperatingwith a groove 28 in the top of the frame so that the frame and sashesare providedwith interlocking weather stops along all their meetinglines. 7

By means of my improvements, I am enabled to produce a window frameprovided with self balancingsashes either of which can be swung inwardat its-top without interfering with the other; either of which may bereadily removed from the frame without disturbing any part of theframeand without removing the other sash; both of which may be raised,lowered, tilted, or

removedwithout causing them to protrude beyond the front stop of theupper sash; all of the operations being carried on entirely from theinside of the window, which is not only a great convenience to theworkman but is a matter of the first importancewhen thewindow isprovided with double sashes oris screened on the outside.

It will be understood that the mechanism for carrying out myimprovements may be modified by substituting equivalents for theslide-bolts, stops guides and other accessories of the'sashes andframes, without departing from the spirit of my invention; and I do notdesire to limit myself simply to the specific forms shown for theseelements, the forms shown being used as illustrations of suitabledevices forthe purposes int-ended. V q

A modification of the attachment for controlling the swinging of theuppersash may be made by attaching a chain 3l to an eye 32 in the 'topofthe sash, the other end of the chain being fastened to a collar 30 whichtravels on a rod 29 fastened to the window stop outside of the sash. pAs the sash is raised and lowered the collar 30 will slip up: and downtherod 29, but the chain will arrest and hold the sash when it is tiltedforward, as shown in Fig. 2. The chain is detachably secured to the rodthrough a hook, so that it may be readily disconnected if that isrequisite forthe convenient manipulation of the sash.

Having thus described my invention, what I claim and desire to secure byLetters lPatent of the United States is V 1. The combination, with awindow frame, having guide grooves in the sides thereof, of a sashhaving sash bottom guides and counterbalance chains traveling in saidguideways, a slidable element embracing one ofsaid chains and a sashcontroller con-1 sash, whereby the sash may 'be-tilted at an,

angle to the vertical and raised and lowered while so tilted. V j V ELOFKLEONARD.
